Birds of Prey: Margot Robbie has promised a diverse cast for the DC movie (Image: DC)

However, Margot Robbie has promised a diverse cast (and as a producer, she has the capability to follow through on this promise) so it's likely Montoya will remain true to her roots.

Cathy Yan, who is best known for writing and directing her feature debut “Dead Pigs,” which took home the World Cinema Dramatic Award For Ensemble Acting at Sundance earlier this year, is tipped to direct.

Yan would be the third female filmmaker to join the DC universe with this film, and the first Asian woman to direct a DC film.

Margot Robbie has been a busy woman, receiving critical acclaim for her portrayal of Tonya Harding and her upcoming role in Mary Queen of Scots.

Christina Hodson wrote the “Birds of Prey” spinoff for Warner Bros which has yet to get a release date.
